onauxclick 特性为 GlobalEventHandlers 混合 EventHandler 为处理 auxclick 事件。

auxclick event is raised when a non-primary button has been pressed on an input device (e.g., a middle mouse button). It fires after the mousedown and mouseup events, in that order.

注意： Browser vendors are implementing this property as part of a plan to improve compatibility with regards to button behaviors. Specifically, event behavior is being updated so that click only fires for primary button clicks (e.g., left mouse button), while auxclick fires for non-primary button clicks. Historically, click has generally fired for the click of any device input button, although with browser behavior being somewhat inconsistent.

句法

target.onauxclick = functionRef;

值

functionRef is a function name or a 函数表达式 . The function receives a MouseEvent object as its sole argument. Within the function, this will be the element upon which the event was triggered.

Only one onauxclick handler can be assigned to an object at a time. You may prefer to use the EventTarget.addEventListener() method instead, since it's more flexible.

范例

In this example we define functions for two event handlers — onclick and onauxclick . The former changes the color of the button background, while the latter changes the button foreground (text) color. You can see the two functions in action by trying the demo out with a multi-button mouse ( see it live on GitHub ; also see the source code ).

var button = document.querySelector('button');
var html = document.querySelector('html');
function random(number) {
  return Math.floor(Math.random() * number);
}
button.onclick = function() {
  var rndCol = 'rgb(' + random(255) + ',' + random(255) + ',' + random(255) + ')';
  button.style.backgroundColor = rndCol;
};
button.onauxclick = function() {
  var rndCol = 'rgb(' + random(255) + ',' + random(255) + ',' + random(255) + ')';
  button.style.color = rndCol;
}

注意 : If you are using a three-button mouse, you'll notice that the onauxclick handler is run when either of the non-left mouse buttons are clicked.
